Flexible electronic displays with touch screens are increasingly used in demanding outdoor environments. Design engineers are challenged to develop optical systems that meet a wide thermal range (–40° to +85°C) and comply with diverse optical, electrical, and mechanical parameters. This article describes possible solutions, including transparent thin‐film anti‐reflective and conductive coatings. Also discussed are technologies being currently employed such as conductive transparent oxides [e.g., indium tin oxide (ITO)], carbon nanotubes, and silver nano‐particles. The optical and mechanical properties of substrates used in the fabrication of flexible displays and touch screens are also reviewed.
